PATENT OFFIC JOSEPH I-IUTOHINSON, OF NEW YORK, N. Y., ASSIGrNOR TO THE KERN BURNER COMPANY, OF NEW YORK, Y., A CORPORATION OF NEW YORK.

GAS-RADIATOR.

SPECIFICATION forming part of Letters Patent No. 763,057, dated June 21, 1904.

Application filed November 3, 1903- Serial No. 179,662, (No model.)

To aZZ whom it may concern:

Be it known that I, J OSEPH HU'IOHINSON, a citizen of the United States, residing at New York city, New York county, New York, have invented certain new and useful Improvements in Gas-Radiators, of which the following is a full, clear, and exact description.

My invention relates to improvements in an artificial heating apparatus, particularly to the construction for heating by radiation, the radiating-surfaces being heated by the direct contact of a gas-flame.

The object of this invention is to construct a simple and reliable device which may be employed in almost any location and connected to a gas-supply for heating rooms, 860.

The construction may be employed without attaching it to a flue, since the products of combustion contain absolutely no poisonous or uncombined gases. The heat which is produced in this manner by radiation is of great penetrating power and much pleasanter to the senses than that accomplished by the simple means of currents of air contacting with a flame.

My invention consists in a construction embodying, essentially, three elements: first,

what is termed a Bunsen burner, which is arranged horizontally and supplied with the gas and air and suitable regulating mechanism; second, a series of tubes formed, prefer 'efficientradiation of heat from the tubes and adjacent surfaces.

The improvements will be readily understood from an inspection of the accompanying two sheets of drawings and the following specification.

Figure 1 is a front elevation of an apparatus embodying the improvements of my invention, suggesting also in dotted outline at one side an ornamental background, which may or may not be employed. Fig. 2 is a vertical section and front elevation of the same device. Fig. 3 is a vertical section and side elevation of the same construction, showing one of the tubes partly in section and indicating by direction of the arrows the currents of air and products of combustion, the air being represented by dotted lines and the products of combustion by dot-and-dash lines;

Fig. 4: is a plan view and cross-section of the same construction, showing a fragment of a connecting-pipe for a gas-supply.

The construction is particularly designed for use on a portable frame havinga suitable standard or base 1, which is substantially horizontal and in the nature of a platform.

2 is the main mixing-chamber of the Bunsen burner, receiving its gas-supply from a tube 3 and its air-supply through the openings 4.

Regulation of the gas-supply, and consequently control of the temperature of the device,is effected by a suitable regulating-screw o. The bunsen is provided with a series of outlets 6, which are cylindrical in form and serve to support the'radiating-tubes 7. These tubes are preferably made of fire-clay and perforated throughout slightly more than one-half of their circumferences in the front, and they also have a few perforations at the rear near the bottom. The tubes are reduced in size at the top and may be freely inserted into suit able openings in the top plate 8 or removed when desired. This top plate 8 is supported by means of the back plate 9, which also serves as a reflecting-surface for the air and products of combustion. The combustible mixture as it passes from the bunsen is ignited and burns inside of the clay tubes 7 ,from which the products of combustion pass through the perforations, the tubes becoming highly incandescent.

The parts thus far described above the platform or base 1 are surrounded on the sides, top, and rear by a casing 10, which serves to direct and confine the products of combustion and insure their complete ignition before their discharge into the room.

11 is a passage through the back plate 9 at the base of the tubes.

12 is a deflector, which extends downward from the top of the casing at the front about on a level with the tops of the tubes. The gases in their highly-heated form when passing upward are deflected by this flange 12 and by the pressure of air at the front, so as to pass upwardly and be forced downward between the back plate 9 and the casing 10. They are delivered between the tubes 7 at the base through the passage 11, so that practically all the gases are returned to the vicinity of the ignition, where they are reheated, and thus completely burn and destroy any foreign particles which might be brought in.

It has been noted in the operation of this stove or radiator without the casing that the ignition when the gas-pressure is low or restricted is such that the tubes are less heated at the top than the bottom. The returning of the gases and the products of combustion to the base of the tubes seems to prolong the area of the heating of the tubes, so that they become hot throughout their entire lengths. It has also been found that when the casing is not used there is a considerable escape of uncombined gases. This is partly due to the contact of cold air. The casing avoids this difliculty.

13 is a second deflector, which is connected to the casing in front of the first deflector 12. This second deflector prevents the more highly-heated products of combustion from passing straight out into the room. The pressure of the atmosphere acting against them forces a large proportion of the currents upward and out through the outlets 14 at the top.

15 is a third deflector rising fromthe top plate 8 and extending from side to side. This assists in effecting the necessary draft and preventing retarding eddies.

This construction has been found to act in a most efficient manner. Its efficiency is high because the consumption of gas is complete, and the radiating-tubes and reflector-surfaces of the casing are so arranged as to utilize practically all of the heat units resulting from the combustion in heating the surrounding air by radiation.

What I claim is 1. A gas-radiator comprising a standard having a base, a Bunsen burner located beneath said base and having a series of discharge-orifices above the base, perforated clay tubes removabl y supported above said orifices, a casing surrounding said tubes at the sides and back and having a down passage back of said tubes, with aconnecting-passage at the base of said tubes and a deflector in front and above said tubes whereby the products of combustion are deflected upward and backward of said tubes and pass outward at the front between said tubes near the base.

2. A gas-radiator comprising a standard having a base, a mixing-chamber beneath said base, means for conveying gas and air to said mixing-chamber, a series of perforatedradiating-tubes supported above said base, a shelf at the top to removably receive the upper ends of said tubes and a casing surrounding the top, sides and back of said tubes and depending at the front in such a manner that the products of combustion are deflected and returned by the tubes for the purpose specified.

3. A gas-radiator comprising a base, a mixing-chamber beneath said base, means for the admission of air and gas to said chamber, a series of radiating-tubes above said base having their interiors connected with said mixing-chamber, and a casing for deflecting the products of combustion and discharging the same at the base of said tubes above the mixing-chamber where they may be heated by the burning gases from inside said tube.

4:. A gas-radiator comprising a base, a Bunsen burner discharging through orifices in said base, a series of radiating-tubes above said base connected with said orifices, a casing surrounding said tubes having a deflecting-flange at the top and in front of said tubes and a second wall with perforations in the top in front of said deflecting-flange for the purpose speci fled.

5. A gas-radiator comprising a base, a Bunsen burner connected therewith, a perforated clay tube removably supported above said base, means for supplying a mixture of gas and air to said tube for ignition within said tube, a casing surrounding said tube at the top, sides and back, and means for deflecting the products of combustion and discharging the same again at the base of said tube from the rear.

6. A gas-radiator comprising a standard, a base therefor, a series of perforated rad iatingtubes supported above said base, means for supplying a mixture of gas and air for ignition in said tubes, and a casing supported by said base surrounding said tubes, and means for deflecting the products of combustion within said casing whereby they return and are brought to pass over the outer surface of said tubes after they have passed out through the perforations therein.
